In reagards to aquos 9, the aquos will have much better clarity, bass and power. The downfall to the aquos is it's size and lack of being water resistant! I would go with the aquos if you can keep it from getting wet!

the jbl extreme is a nice bluetooth speaker , however the aiwa exos 9 is much louder better bass . i own the exos 9 , this speaker is really loud . i'm trying to get two of them. go to youtube and check out the reviews to get more info

The battery of the XTREME normally charges from 0 to full in 3.5 hours using the cable provided. And is rated to give up to 15-hours of playtime depending on volume level, the type of audio you are playing and the method of connection (Bluetooth or Wired).

Has anyone has used this speaker in a running boat? I want to know that it can be clearly heard at say 40mph with a 4 stroke outboard running. (5 Answers)

Well, personally I would not use this speaker while running across the lake at 40MPH. We have a Tri-toon with a 250 Yamaha SHO 4 stroke. Even though that is a quiet engine, you still have the wind, water, etc making all the other noise. What I depend on is my custom built 2000 watt system to give us our listening enjoyment while under way. I'm going to be using this JBL extreme when we are sitting still in party cove so I don't run my 2 batteries down on the boat. I do have a battery isolator, but I've already ran my second battery down to dead a couple of times with the 2000 watt system running at about 1/4 volume. So this JBL Xtreme does the trick while sitting still and is plenty loud to be heard in the boat and while we are swimming in the water. Good question and I hope this helps!

I Bought 2 for my boat this weekend. I could clearly hear the music at 3500 RPM's with a inboard/outboard 6 cylinder. Don't expect it to shake your bones, but a great option for a speaker you can use I and out of the boat

If the XTREME is used when fully charged, it should last up to 15 hours. However, speaker play time will vary due to certain reasons such as genre of music being played and volume level. So if the XTREME is playing music with loud bass and the volume is at 100%, the battery would drain faster than when you are playing mellow or soft music and the volume is at 50%.

Windows 7 or later.
Click start
type BLUETOOTH into the search bar
open your bluetooth devices and click add a device

On the speaker press the bluetooth connectivity button until you hear the chime. (you may need to hold this button for a few seconds, i can not recall.)

I found if I'm playing music at 100% I would get an average battery time of 9-10hrs and if I play it at 50% I would get an average battery time of 18-19hr and that's with my jump drive plugged in for music stored on there and charging my iPhone 6s Plus when it's at 5%. So it's great for me and I use it for everything g and even take it out on the my flats boat.
